Chiral Mn(salen) complex 3 bearing a 1-ethyl-1-methyl-propyl group at C3, C3′, C5, and C5′ was found to induce higher asymmetry in the epoxidation of conjugated Z-olefins, especially less nucleophilic ones, in the presence of 4-phenylpyridine N-oxide than complex 1 bearing a t-butyl group at the same carbons. The higher enantioselectivity was considered to be attributable to Me-in-plane conformation of the 1-ethyl-1-methylpropyl group at C3 and C3′.
